[Samba] windows explorer lockup

When exploring a share served by Samba 3.0.8 from Windows 2000, explorer 
will frequently lock up for exactly 10 seconds. A packet capture reveals 
that windows tries to open a directory as a file (create andx request) 
with samba responding STATUS_FILE_IS_A_DIRECTORY. After a few attempts 
of create andx windows waits for 10 seconds and then creates a new 
connection to samba and everything works again for a little while and 
then the whole process repeats.

Why is windows treating a directory as a file, when requesting 
information for the path samba indicates that it is a directory. Is this 
an explorer bug?

The packet dump can be found at


The first erroneous request is in packet 43, the 10 second pause starts 
after packet 87.
